Property Value

The number of elements actually contained in the ArrayList.

Remarks

Capacity is the number of elements that the ArrayList can store. Count is the number of elements that are actually in the ArrayList.

Capacity is always greater than or equal to Count. If Count exceeds Capacity while adding elements, the capacity is automatically increased by reallocating the internal array before copying the old elements and adding the new elements.

Retrieving the value of this property is an O(1) operation.
